CROWN CASTLE INTERNATIONAL CORP. AND SUBSIDIARIES
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS-Unaudited
(Tabular dollars in millions, except per share amounts)

1.General
The information contained in the following notes to the condensed consolidated financial statements is condensed from that which would appear in the annual consolidated financial statements; accordingly, the condensed consolidated financial statements included herein should be reviewed in conjunction with the consolidated financial statements for the fiscal year ended December 31, 2021, and related notes thereto, included in the 2021 Form 10-K filed by Crown Castle International Corp. ("CCIC") with the SEC. Capitalized terms used but not defined in these notes to the condensed consolidated financial statements have the same meaning given to them in the 2021 Form 10-K. References to the "Company" refer to CCIC and its predecessor, as applicable, and their subsidiaries, unless otherwise indicated or the context indicates otherwise. As used herein, the term "including," and any variation thereof means "including without limitation." The use of the word "or" herein is not exclusive. Unless the context suggests otherwise, references to "U.S." are to the United States of America and Puerto Rico, collectively.
The Company owns, operates and leases shared communications infrastructure that is geographically dispersed throughout the U.S., including (1) towers and other structures, such as rooftops (collectively, "towers"), and (2) fiber primarily supporting small cell networks ("small cells") and fiber solutions. The Company's towers, fiber and small cells assets are collectively referred to herein as "communications infrastructure," and the Company's customers on its communications infrastructure are referred to herein as "tenants."
The Company's core business is providing access, including space or capacity, to its shared communications infrastructure via long-term contracts in various forms, including lease, license, sublease and service agreements (collectively, "tenant contracts").
The Company's operating segments consist of (1) Towers and (2) Fiber. See note 10.
As part of the Company's effort to provide comprehensive communications infrastructure solutions, as an ancillary business, the Company also offers certain services primarily relating to its Towers segment, predominately consisting of (1) site development services primarily relating to existing or new tenant equipment installations, including: site acquisition, architectural and engineering, or zoning and permitting (collectively, "site development services") and (2) tenant equipment installation or subsequent augmentations (collectively, "installation services").
The Company operates as a REIT for U.S. federal income tax purposes. In addition, the Company has certain taxable REIT subsidiaries ("TRSs"). See note 6.
Approximately 53% of the Company's towers are leased or subleased or operated and managed under master leases, subleases, and other agreements with AT&T and T-Mobile, including agreements assumed by T-Mobile following its merger with Sprint completed on April 1, 2020. The Company has the option to purchase these towers at the end of their respective lease terms. The Company has no obligation to exercise such purchase options.
Basis of Presentation
The condensed consolidated financial statements included herein are unaudited; however, they include all adjustments (consisting only of normal recurring adjustments) which, in the opinion of management, are necessary to state fairly the condensed consolidated financial position of the Company at March 31, 2022, the condensed consolidated results of operations for the three months ended March 31, 2022 and 2021, and the condensed consolidated cash flows for the three months ended March 31, 2022 and 2021. The year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. The results of operations for the interim periods presented are not necessarily indicative of the results to be expected for the full year.
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

2.Summary of Significant Accounting Policies
Recently Adopted Accounting Pronouncements
No accounting pronouncements adopted during the three months ended March 31, 2022 had a material impact on the Company's condensed consolidated financial statements.
Recent Accounting Pronouncements Not Yet Adopted
No new accounting pronouncements issued but not yet adopted are expected to have a material impact on the Company's condensed consolidated financial statements.
3.Revenues
Site Rental Revenues
The Company generates site rental revenues from its core business by providing tenants with access, including space or capacity, to its shared communications infrastructure via long-term tenant contracts in various forms, including lease, license, sublease and service agreements. Providing such access over the length of the tenant contract term represents the Company’s sole performance obligation under its tenant contracts.
Site rental revenues from the Company's tenant contracts are recognized on a straight-line, ratable basis over the fixed, non-cancelable term of the relevant tenant contract, which generally ranges from five to 15 years for wireless tenants and three to 20 years for the Company's fiber solutions tenants (including from organizations with high-bandwidth and multi-location demands), regardless of whether the payments from the tenant are received in equal monthly amounts during the life of the tenant contract. Certain of the Company's tenant contracts contain (1) fixed escalation clauses (such as fixed dollar or fixed percentage increases) or inflation-based escalation clauses (such as those tied to the CPI), (2) multiple renewal periods exercisable at the tenant's option and (3) only limited termination rights at the applicable tenant's option through the current term. If the payment terms call for fixed escalations, upfront payments, or rent-free periods, the revenue is recognized on a straight-line basis over the fixed, non-cancelable term of the agreement. When calculating its straight-line rental revenues, the Company considers all fixed elements of tenant contractual escalation provisions, even if such escalation provisions contain a variable element in addition to a minimum. The Company's assets related to straight-line site rental revenues include current amounts of $105 million included in "Other current assets" and non-current amounts of $1.7 billion included in "Deferred site rental receivables" as of March 31, 2022. Amounts billed or received prior to being earned are deferred and reflected in "Deferred revenues" and "Other long-term liabilities." Amounts to which the Company has an unconditional right to payment, which are related to both satisfied or partially satisfied performance obligations, are recorded within "Receivables, net" on the Company's condensed consolidated balance sheet.
Services and Other Revenues
As part of the Company’s effort to provide comprehensive communications infrastructure solutions, as an ancillary business, the Company offers certain services primarily relating to its Towers segment, predominately consisting of (1) site development services and (2) installation services. Upon contract commencement, the Company assesses its services to tenants and identifies performance obligations for each promise to provide a distinct service.
The Company may have multiple performance obligations for site development services, which primarily include: structural analysis, zoning, permitting and construction drawings. For each of these performance obligations, services revenues are recognized at completion of the applicable performance obligation, which represents the point at which the Company believes it has transferred goods or services to the tenant. The revenue recognized is based on an allocation of the transaction price among the performance obligations in a respective contract based on estimated standalone selling price. The volume and mix of site development services may vary among contracts and may include a combination of some or all of the above performance obligations. Payments generally are due within 45 to 60 days and generally do not contain variable-consideration provisions. The transaction price for the Company's tower installation services consists of amounts for (1) permanent improvements to the Company's towers that represent a lease component and (2) the performance of the service. Amounts under the Company's tower installation service agreements that represent a lease component are recognized as site rental revenues on a straight-line basis over the length of the associated estimated lease term. For the performance of the installation service, the Company has one performance obligation, which is satisfied at the time of the applicable installation or augmentation and recognized as services and other revenues. Since performance obligations are typically satisfied prior to receiving payment from tenants, the unconditional right to payment is recorded within "Receivables, net" on the Company’s

condensed consolidated balance sheet. The vast majority of the Company’s services generally have a duration of one year or less.
Additional Information on Revenues
As of January 1, 2022 and March 31, 2022, $2.6 billion and $2.5 billion, respectively, of unrecognized revenue was reported in "Deferred revenues" and "Other long-term liabilities" on the Company's condensed consolidated balance sheet. During the three months ended March 31, 2022, approximately $190 million of the January 1, 2022 unrecognized revenue balance was recognized as revenue. During the three months ended March 31, 2021, approximately $170 million of the January 1, 2021 unrecognized revenue balance was recognized as revenue.
The following table is a summary of the non-cancelable contracted amounts owed to the Company by tenants pursuant to tenant contracts in effect as of March 31, 2022.

(b)If the respective series of Tower Revenue Notes are not paid in full on or prior to an applicable anticipated repayment date, then Excess Cash Flow (as defined in the indenture) of the issuers of such notes will be used to repay principal of the applicable series and class of the Tower Revenue Notes, and additional interest (of an additional approximately 5% per annum) will accrue on the respective Tower Revenue Notes. As of March 31, 2022, the Tower Revenue Notes have principal amounts of $700 million and $750 million, with anticipated repayment dates in 2025 and 2028, respectively.
(c)The Company's finance leases and other obligations relate to land, fiber, vehicles, and other assets and bear interest rates ranging up to 10% and mature in periods ranging from less than one year to approximately 25 years.
(d)As of March 31, 2022, the undrawn availability under the 2016 Revolver was $4.1 billion.
(e)Both the 2016 Revolver and 2016 Term Loan A bear interest, at the Company's option, at either (1) LIBOR plus a credit spread ranging from 0.875% to 1.750% per annum or (2) an alternate base rate plus a credit spread ranging from 0.000% to 0.750% per annum, in each case, with the applicable credit spread based on the Company's senior unsecured debt rating. The Company pays a commitment fee ranging from 0.080% to 0.300%, based on the Company's senior unsecured debt rating, per annum on the undrawn available amount under the 2016 Revolver. See the 2021 Form 10-K, including note 7 to the consolidated financial statements, for information regarding (1) potential adjustments to such percentages and (2) LIBOR transition provisions.

(f)In March 2022, the Company increased the size of its CP Program to permit the issuance of Commercial Paper Notes in an aggregate principal amount not to exceed $2.0 billion at any time outstanding. Notes under the CP Program may be issued, repaid and re-issued from time to time. The net proceeds of the Commercial Paper Notes are expected to be used for general corporate purposes. The maturities of the Commercial Paper Notes, when outstanding, may vary but may not exceed 397 days from the date of issue. The Commercial Paper Notes are issued under customary terms in the commercial paper market and are issued at a discount from par or, alternatively, can be issued at par and bear varying interest rates on a fixed or floating basis. As of March 31, 2022, the Company had net issuances of $1.0 billion under the CP Program. At any point in time, the Company intends to maintain available commitments under its 2016 Revolver in an amount at least equal to the amount of Commercial Paper Notes outstanding. While any outstanding Commercial Paper Notes generally have short-term maturities, the Company classifies the outstanding issuances, when applicable, as long-term based on its ability and intent to refinance the outstanding issuances on a long-term basis.
(g)In March 2022, the Company issued $750 million aggregate principal amount of 2.900% senior unsecured notes due 2027 ("March 2022 Senior Notes"). The Company used the net proceeds from the March 2022 Senior Notes offering to repay a portion of the outstanding indebtedness under its CP Program and pay related fees and expenses.
(h)In March 2022, the Company (1) prepaid in full the previously outstanding Tower Revenue Notes, Series 2018-1 and (2) redeemed in full the previously outstanding 3.849% Secured Notes.

The fair value of cash and cash equivalents and restricted cash approximate the carrying value. The Company determines the fair value of its debt securities based on indicative, non-binding quotes from brokers. Quotes from brokers require judgment and are based on the brokers' interpretation of market information, including implied credit spreads for similar borrowings on recent trades or bid/ask prices or quotes from active markets if available. Since December 31, 2021, there have been no changes in the Company's valuation techniques used to measure fair values.
6.Income Taxes
The Company operates as a REIT for U.S. federal income tax purposes. As a REIT, the Company is generally entitled to a deduction for dividends that it pays and therefore is not subject to U.S. federal corporate income tax on its net taxable income that is currently distributed to its stockholders. The Company also may be subject to certain federal, state, local and foreign taxes on its income and assets, including (1) taxes on any undistributed income, (2) taxes related to the TRSs, (3) franchise taxes, (4) property taxes, and (5) transfer taxes. In addition, the Company could under certain circumstances be required to pay an excise or penalty tax, which could be significant in amount, in order to utilize one or more relief provisions under the Internal Revenue Code of 1986, as amended, to maintain qualification for taxation as a REIT.
The Company's TRS assets and operations will continue to be subject, as applicable, to federal and state corporate income taxes or to foreign taxes in the jurisdictions in which such assets and operations are located. The Company's foreign assets and operations (including its tower operations in Puerto Rico) are subject to foreign income taxes in the jurisdictions in which such assets and operations are located, regardless of whether they are included in a TRS or not.
For the three months ended March 31, 2022 and 2021, the Company's effective tax rate differed from the federal statutory rate predominately due to the Company's REIT status, including the dividends paid deduction.
7.Per Share Information
Basic net income (loss), per common share, excludes dilution and is computed by dividing net income (loss) by the weighted-average number of common shares outstanding during the period. For the three months ended March 31, 2022 and 2021, diluted net income (loss), per common share, is computed by dividing net income (loss) by the weighted-average number of common shares outstanding during the period, plus any potential dilutive common share equivalents, including shares issuable upon the vesting of restricted stock units as determined under the treasury stock method.

The Company has received notices of claims and has been named as one of several defendants in lawsuits stemming from an April 2019 gas leak explosion in Durham, North Carolina, which occurred near an area where the Company's subcontractors were installing fiber. The explosion resulted in two fatalities, physical injuries (some of which were serious), and property damage to surrounding buildings and businesses. Currently, the Company is unable to determine the likelihood of an outcome or estimate a range of possible losses, if any, related to these lawsuits.
New York State Department of Transportation
In 2019, the State of New York passed legislation authorizing the Department of Transportation ("NYSDOT") to enter into agreements with any fiber provider for the use and occupancy of the state right-of-way for fiber optic lines. The legislation authorized the NYSDOT to charge a fee of up to fair market value for such use and occupancy. The Company paid fees relating to newly deployed fiber lines but has not been required to pay, and has not recognized any costs in connection with, any fees relating to previously deployed fiber lines. In April 2022, the State repealed the legislation that authorized the fees. The repeal does not give rise to any right to receive a refund of previously paid fees.
Other Matters
The Company is involved in various other claims, assessments, lawsuits or proceedings arising in the ordinary course of business. While there are uncertainties inherent in the ultimate outcome of such other matters and it is impossible to presently determine the ultimate costs or losses that may be incurred, if any, management believes the adverse resolution of such uncertainties and the incurrence of such costs should not have a material adverse effect on the Company's condensed consolidated financial position or results of operations. Additionally, the Company and certain of its subsidiaries are contingently liable for commitments or performance guarantees arising in the ordinary course of business, including certain letters of credit or surety bonds. In addition, see note 1 for a discussion of the Company's option to purchase approximately 53% of its towers at the end of their respective lease terms. The Company has no obligation to exercise such purchase options.

2021 "At-the-Market" Stock Offering Program
In March 2021, the Company established an "at-the-market" stock offering program through which it may issue and sell shares of its common stock having an aggregate gross sales price of up to $750 million ("2021 ATM Program"). Sales under the 2021 ATM Program may be made by means of ordinary brokers' transactions on the NYSE or otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices or, subject to the Company's specific instructions, at negotiated prices. The Company intends to use the net proceeds from any sales under the 2021 ATM Program for general corporate purposes, which may include (1) the funding of future acquisitions or investments or (2) the repayment or repurchase of any outstanding indebtedness. The Company has not sold any shares of common stock under the 2021 ATM Program.
10.Operating Segments
The Company's operating segments consist of (1) Towers and (2) Fiber. The Towers segment provides access, including space or capacity, to the Company's more than 40,000 towers geographically dispersed throughout the U.S. The Towers segment also reflects certain ancillary services relating to the Company's towers, predominately consisting of site development services and installation services. The Fiber segment provides access, including space or capacity, to the Company's more than 80,000 route miles of fiber primarily supporting small cell networks and fiber solutions geographically dispersed throughout the U.S.
The measurements of profit or loss used by the Company's chief operating decision maker ("CODM") to evaluate the performance of its operating segments are (1) segment site rental gross margin, (2) segment services and other gross margin and (3) segment operating profit. The Company defines segment site rental gross margin as segment site rental revenues less segment site rental costs of operations, excluding stock-based compensation expense and amortization of prepaid lease purchase price adjustments recorded in consolidated site rental costs of operations. The Company defines segment services and other gross margin as segment services and other revenues less segment services and other costs of operations, excluding stock-based compensation expense recorded in consolidated services and other costs of operations. The Company defines segment operating profit as segment site rental gross margin plus segment services and other gross margin, and segment other operating (income) expense, less selling, general and administrative expenses attributable to the respective segment. All of these measurements of profit or loss are exclusive of depreciation, amortization and accretion, which are shown separately.
The following tables set forth the Company's segment operating results for the three months ended March 31, 2022 and 2021. Costs that are directly attributable to Towers and Fiber are assigned to those respective segments. Additionally, certain costs are shared across segments and are reflected in the Company's segment measures through allocations that management believes to be reasonable. The "Other" column (1) represents amounts excluded from specific segments, such as asset write-down charges, acquisition and integration costs, depreciation, amortization and accretion, amortization of prepaid lease purchase price adjustments, interest expense and amortization of deferred financing costs, gains (losses) on retirement of long-term obligations, interest income, other income (expense), income (loss) from discontinued operations, and stock-based compensation expense, and (2) reconciles segment operating profit to income (loss) before income taxes, as the amounts are not utilized in assessing each segment’s performance. The "Other" total assets balance includes corporate assets such as cash and cash equivalents which have not been allocated to specific segments. There are no significant revenues resulting from transactions between the Company's operating segments.

ITEM 2.MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following discussion should be read in conjunction with the response to Part I, Item 1 of this report and the consolidated financial statements of the Company including the related notes and "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations" ("MD&A") included in the 2021 Form 10-K.
General Overview
Overview
We own, operate and lease shared communications infrastructure that is geographically dispersed throughout the U.S., including more than (1) 40,000 towers and (2) 80,000 route miles of fiber primarily supporting small cells and fiber solutions.
Our towers have a significant presence in the top 100 basic trading areas ("BTAs"), and the majority of our small cells and fiber are located in major metropolitan areas. Site rental revenues represented 90% of our first quarter 2022 consolidated net revenues. Our Towers segment and Fiber segment accounted for 68% and 32%, respectively, of our first quarter 2022 site rental revenues. Within our Fiber segment, 69% and 31% of our first quarter 2022 Fiber site rental revenues related to fiber solutions and small cells, respectively. See note 10 to our condensed consolidated financial statements. The vast majority of our site rental revenues are of a recurring nature and are derived from long-term tenant contracts with our tenants.
Strategy
As a leading provider of shared communications infrastructure in the U.S., our strategy is to create long-term stockholder value via a combination of (1) growing cash flows generated from our existing portfolio of communications infrastructure, (2) returning a meaningful portion of our cash generated by operating activities to our common stockholders in the form of dividends and (3) investing capital efficiently to grow cash flows and long-term dividends per share. Our strategy is based, in part, on our belief that the U.S. is the most attractive market for shared communications infrastructure investment with the greatest long-term growth potential. We measure our efforts to create "long-term stockholder value" by the combined payment of dividends to stockholders and growth in our per-share results. The key elements of our strategy are to:
Grow cash flows from our existing communications infrastructure. We are focused on maximizing the recurring site rental cash flows generated from providing our tenants with long-term access to our shared infrastructure assets, which we believe is the core driver of value for our stockholders. Tenant additions or modifications of existing tenant equipment (collectively, "tenant additions") enable our tenants to expand coverage and capacity in order to meet increasing demand for data while generating high incremental returns for our business. We believe our product offerings of towers and small cells provide a comprehensive solution to our wireless tenants' growing network needs through our shared communications infrastructure model, which is an efficient and cost-effective way to serve our tenants. Additionally, we believe our ability to share our fiber assets across multiple tenants to deploy both small cells and offer fiber solutions allows us to generate cash flows and increase stockholder return.
Return cash generated by operating activities to common stockholders in the form of dividends. We believe that distributing a meaningful portion of our cash generated by operating activities appropriately provides common stockholders with increased certainty for a portion of expected long-term stockholder value while still allowing us to retain sufficient flexibility to invest in our business and deliver growth. We believe this decision reflects the translation of the high-quality, long-term contractual cash flows of our business into stable capital returns to common stockholders.
Invest capital efficiently to grow cash flows and long-term dividends per share. In addition to adding tenants to existing communications infrastructure, we seek to invest our available capital, including the net cash generated by our operating activities and external financing sources, in a manner that will increase long-term stockholder value on a risk-adjusted basis. These investments include constructing and acquiring new communications infrastructure that we expect will generate future cash flow growth and attractive long-term returns by adding tenants to those assets over time. Our historical investments have included the following (in no particular order):
construction of towers, fiber and small cells;
acquisitions of towers, fiber and small cells;
acquisitions of land interests (which primarily relate to land assets under towers);
improvements and structural enhancements to our existing communications infrastructure;
purchases of shares of our common stock from time to time; and
17


purchases, repayments or redemptions of our debt.
Our strategy to create long-term stockholder value is based on our belief that there will be considerable future demand for our communications infrastructure based on the location of our assets and the rapid growth in the demand for data. We believe that such demand for our communications infrastructure will continue, will result in growth of our cash flows due to tenant additions on our existing communications infrastructure, and will create other growth opportunities for us, such as demand for newly constructed or acquired communications infrastructure, as described above. Further, we seek to augment the long-term value creation associated with growing our recurring site rental cash flows by offering certain ancillary site development and installation services within our Towers segment.
Highlights of Business Fundamentals and Results
We operate as a REIT for U.S. federal income tax purposes
As a REIT, we are generally entitled to a deduction for dividends that we pay and therefore are not subject to U.S. federal corporate income tax on our taxable income that is distributed to our stockholders.
To remain qualified and taxed as a REIT, we will generally be required to annually distribute to our stockholders at least 90% of our REIT taxable income, after the utilization of our NOLs (determined without regard to the dividends paid deduction and excluding net capital gain).
See note 6 to our condensed consolidated financial statements for further discussion of our REIT status.
Potential growth resulting from the increasing demand for data
We expect existing and potential new tenant demand for our communications infrastructure will result from (1) new technologies, (2) increased usage of mobile entertainment, mobile internet, and machine-to-machine applications, (3) adoption of other emerging and embedded wireless devices (including smartphones, laptops, tablets, wearables and other devices), (4) increasing smartphone penetration, (5) wireless carrier focus on expanding both network quality and capacity, including the use of both towers and small cells, (6) the adoption of other bandwidth-intensive applications (such as cloud services and video communications), (7) the availability of additional spectrum and (8) increased government initiatives to support connectivity throughout the U.S.
We expect U.S. wireless carriers will continue to focus on improving network quality and expanding capacity (including through 5G initiatives) by utilizing a combination of towers and small cells. We believe our product offerings of towers and small cells provide a comprehensive solution to our wireless tenants' growing communications infrastructure needs.
We expect organizations will continue to increase the usage of high-bandwidth applications that will require the utilization of more fiber infrastructure and fiber solutions, such as those we provide.
Within our Fiber segment, we are able to generate growth and returns for our stockholders by deploying our fiber for both small cells and fiber solutions tenants.
Tenant additions on our existing communications infrastructure are achieved at a low incremental operating cost, delivering high incremental returns.
Substantially all of our communications infrastructure can accommodate additional tenancy, either as currently constructed or with appropriate modifications.
Investing capital efficiently to grow long-term dividends per share (see also "Item 2. MD&A—General Overview—Strategy")
Discretionary capital expenditures of $260 million for the three months ended March 31, 2022, predominately resulting from the construction of new communications infrastructure and improvements to existing communications infrastructure in order to support additional tenants.
We expect to continue to construct and acquire new communications infrastructure based on our tenants' needs and generate attractive long-term returns by adding additional tenants over time.
Site rental revenues under long-term tenant contracts
Initial terms of five to 15 years for site rental revenues derived from wireless tenants, with contractual escalations and multiple renewal periods, exercisable at the option of the tenant, of five to 10 years each.
On January 6, 2022, we entered into a 12-year agreement with T-Mobile ("T-Mobile Agreement), which includes contracted new tower leasing activity and a base escalator that is consistent with historical levels for our Towers segment. The T-Mobile Agreement also includes a contractual commitment by T-Mobile for 35,000 new small cell nodes, including specific commitments in each of the next five years.
Initial terms that generally vary between three to 20 years for site rental revenues derived from our fiber solutions tenants (including from organizations with high-bandwidth and multi-location demands).
18


Weighted-average remaining term of approximately five years, exclusive of renewals exercisable at the tenants' option, currently representing approximately $42 billion of expected future cash inflows.
Majority of our revenues from large wireless carriers
Approximately three-fourths of our site rental revenues were derived from T-Mobile, AT&T and Verizon Wireless for the three months ended March 31, 2022.
Majority of land under our towers under long-term control
Approximately 90% of our Towers site rental gross margin and approximately 80% of our Towers site rental gross margin is derived from towers located on land that we own or control for greater than 10 and 20 years, respectively. The aforementioned percentages include towers located on land that is owned, including through fee interests and perpetual easements, which represent approximately 40% of our Towers site rental gross margin.
Majority of our fiber assets are located in major metropolitan areas and are on public rights-of-way.
Minimal sustaining capital expenditure requirements
Sustaining capital expenditures represented approximately 1% of net revenues.
Debt portfolio with long-dated maturities extended over multiple years, with the vast majority of such debt having a fixed rate (see note 4 to our condensed consolidated financial statements and "Item 3. Quantitative and Qualitative Disclosures About Market Risk" for a further discussion of our debt)
As of March 31, 2022, our outstanding debt had a weighted-average interest rate of 3.0% and weighted-average maturity of approximately nine years (assuming anticipated repayment dates on our outstanding Tower Revenue Notes).
85% of our debt has fixed rate coupons.
Our debt service coverage and leverage ratios are within their respective financial maintenance covenants.
During 2022, we completed the following financing activities (see note 4 to our condensed consolidated financial statements)
In March 2022, we increased the size of our CP Program to permit the issuance of Commercial Paper Notes in an aggregate principal amount not to exceed $2.0 billion at any time outstanding. Notes under the CP Program may be issued, repaid and re-issued from time to time.
In March 2022, we issued $750 million aggregate principal amount of 2.900% senior unsecured notes due 2027 ("March 2022 Senior Notes"). We used the net proceeds from the March 2022 Senior Notes offering to repay a portion of the outstanding indebtedness under our CP Program and pay related fees and expenses.
In March 2022, we (1) prepaid in full the previously outstanding Tower Revenue Notes, Series 2018-1 and (2) redeemed in full the previously outstanding 3.849% Secured Notes.
Significant cash flows from operations
Net cash provided by operating activities was $558 million for the three months ended March 31, 2022.
In addition to the positive impact of contractual escalators, we expect to grow our core business of providing access to our communications infrastructure as a result of future anticipated additional demand for our communications infrastructure.
Returning cash flows provided by operations to stockholders in the form of dividends
During the first quarter of 2022, we paid a common stock dividend of $1.47 per share, totaling approximately $650 million.
We currently expect our common stock dividends over the next 12 months to be a cumulative amount of at least $5.88 per share, or an aggregate amount of approximately $2.5 billion.
Over time, we expect to increase our dividend per share generally commensurate with our growth in cash flows. Any future common stock dividends are subject to declaration by our board of directors. See note 9 to our condensed consolidated financial statements for further information regarding our common stock and dividends.
Outlook Highlights
The following are certain highlights of our full year 2022 outlook that impact our business fundamentals described above.
We expect that, when compared to full year 2021, our full year 2022 site rental revenue will be positively impacted by tenant additions, as large wireless carriers and fiber solutions tenants continue to focus on meeting the increasing demand for data.
We expect to continue to invest a meaningful amount of our available capital in the form of discretionary capital expenditures for 2022 based on the anticipated returns on such discretionary investments.
We also expect sustaining capital expenditures to remain approximately 2% of net revenues for full year 2022, consistent with historical annual levels.
19


We expect the T-Mobile Agreement to result in at least $250 million of additional straight-lined revenues for the year ended December 31, 2022. See the 2021 Form 10-K for further discussion of the T-Mobile Agreement, including a discussion of the future expected impact from the T-Mobile and Sprint network consolidation contemplated in the T-Mobile Agreement.
COVID-19
We do not believe that COVID-19 had a material impact on our financial position, results of operations and cash flows during the three months ended March 31, 2022. Given the Company’s access to various sources of liquidity and no near term debt maturities other than Commercial Paper Notes and principal payments on amortizing debt, we currently anticipate that we will be able to maintain sufficient liquidity as we manage through the current environment. See also "Item 2. MD&A—Liquidity and Capital Resources—Liquidity Position" and "Item 1A. Risk Factors" of the 2021 Form 10-K.
We have reopened our offices during the first quarter of 2022. We will continue to actively monitor health and safety concerns relating to COVID-19 and may take further actions as may be required by governmental authorities or advised by public health officials or that we determine are in the best interests of our employees, tenants, business partners and stockholders.
Results of Operations
The following discussion of our results of operations should be read in conjunction with our condensed consolidated financial statements and the 2021 Form 10-K.
The following discussion of our results of operations is based on our condensed consolidated financial statements prepared in accordance with GAAP, which requires us to make estimates and judgments that affect the reported amounts (see "Item 2. MD&A—Accounting and Reporting Matters—Critical Accounting Policies and Estimates" and note 2 to our consolidated financial statements in the 2021 Form 10-K). See "Item 2. MD&A—Accounting and Reporting Matters—Non-GAAP and Segment Financial Measures" for a discussion of our use of (1) segment site rental gross margin, (2) segment services and other gross margin, (3) segment operating profit, including their respective definitions, and (4) Adjusted EBITDA, including its definition, and a reconciliation to income (loss) from continuing operations.
Our operating segments consist of (1) Towers and (2) Fiber. See note 10 to our condensed consolidated financial statements for further discussion of our operating segments.

Site rental revenues grew $207 million, or 15%, for the three months ended March 31, 2022 compared to the three months ended March 31, 2021. This growth was predominately comprised of the factors depicted in the chart below:
(In millions of dollars)
https://cdn.kscope.io/69686060aeac9bb7281cb9334022a034-cci-20220331_g2.jpg
(a)Represents site rental revenues growth from tenant additions across our entire portfolio and renewals or extensions of tenant contracts, exclusive of the impacts from both straight-line accounting and amortization of prepaid rent in accordance with GAAP.
(b)Prepaid rent amortization includes amortization of up-front payments received from long-term tenant contracts and other deferred credits.
(c)Represents the contribution from recent acquisitions until the one-year anniversary of the acquisition.
Towers site rental revenues for the first quarter of 2022 were $1.1 billion and increased by $180 million, or 20%, from $895 million during the same period in the prior year. The increase in Towers site rental revenues was impacted by the following items, inclusive of straight-line accounting (including the impact of the T-Mobile Agreement): tenant additions across our entire portfolio, renewals or extensions of tenant contracts, escalations and non-renewals of tenants contracts. Tenant additions were influenced by our tenants' ongoing efforts to improve network quality and capacity.
Fiber site rental revenues for the first quarter of 2022 were $501 million and increased by $27 million, or 6%, from $474 million during the same period in the prior year. The increase in Fiber site rental revenues was predominately impacted by the increased demand for small cells and fiber solutions. Increased demand for small cells was driven by our tenants' network strategy in an effort to provide capacity and relieve network congestion, and increased demand for fiber solutions was driven by increasing demand for data.
The increase in Towers site rental gross margin from the first quarter of 2021 to the first quarter of 2022 was related to the previously-mentioned 20% increase in Towers site rental revenues and relatively fixed costs to operate our towers.
Towers services and other gross margin was $54 million for the first quarter of 2022 and increased by $19 million from $35 million during the same period in the prior year, which is a reflection of the increased volume of activity from carriers' network enhancements and the volume and mix of services and other work. Our services and other offerings are of a variable nature as these revenues are not under long-term contracts.
Selling, general and administrative expenses for the first quarter of 2022 were $181 million and increased by $17 million, or 10%, from $164 million during the same period in the prior year. The increase in selling, general and administrative expenses was primarily related to the growth in our business.
21


Towers operating profit for the first quarter of 2022 increased by $183 million, or 26%, from the same period in the prior year. The increase in Towers operating profit was primarily related to the growth in our Towers site rental revenues and relatively fixed costs to operate our towers as well as the previously-mentioned increase in Towers services and other gross margin.
Fiber operating profit increased by $23 million, or 9% for the first quarter of 2022 from the same period in the prior year. The increase in Fiber operating profit was primarily related to the previously-mentioned growth in our Fiber site rental revenues.
Depreciation, amortization and accretion was approximately $420 million for first quarter of 2022 and increased by $12 million, or 3% during the same period in the prior year. This increase predominately resulted from a corresponding increase in our gross property and equipment due to capital expenditures.
Interest expense and amortization of deferred financing costs were $164 million for the first quarter of 2022 and decreased by $6 million, or 4%, from $170 million during the same period in the prior year. The decrease predominately resulted from a reduction in the weighted-average interest rate on our debt as a result of our refinancing activities. See note 4 to our condensed consolidated financial statements and "Item 3. Quantitative and Qualitative Disclosures About Market Risk" for a further discussion of our debt.
As a result of repaying certain of our indebtedness in conjunction with our refinancing activities, we incurred losses on retirement of long-term obligations of $26 million and $143 million during the first quarter of 2022 and 2021, respectively. See note 4 to our condensed consolidated financial statements.
For the first quarter of 2022 and 2021, the effective tax rate differs from the federal statutory rate predominately due to our REIT status, including the dividends paid deduction.  See note 6 to our condensed consolidated financial statements and also note 9 to our consolidated financial statements in the 2021 Form 10-K.
Income from continuing operations was $421 million during the first quarter of 2022 compared to $121 million during the first quarter of 2021. The increase was predominately related to (1) growth in our site rental activities in both our Towers and Fiber segments, (2) decrease in losses on retirement of long-term obligations and (3) the previously-mentioned increase in Towers services activity, partially offset by an increase in expenses, including (1) selling, general and administrative expenses and (2) depreciation, amortization and accretion.
Loss from discontinued operations, net of tax, was $63 million during the first quarter of 2021 due to the ATO Settlement. See note 9 to our consolidated financial statements in the 2021 Form 10-K.
Net income was $421 million during the first quarter of 2022 compared to $58 million during the first quarter of 2021. The increase was due to (1) the previously-mentioned increase in income from continuing operations and (2) the previously-mentioned loss from discontinued operations, net of tax, recorded during the first quarter of 2021.
Adjusted EBITDA increased $198 million, or 22%, from the first quarter of 2021 to the first quarter of 2022, reflecting the growth in our site rental activities in both our Towers and Fiber segments as well as the previously-mentioned increase in Towers services activity.
Liquidity and Capital Resources
Overview
General. Our core business generates revenues under long-term tenant contracts (see "Item 2. MD&A—General Overview—Overview") from (1) the largest U.S. wireless carriers and (2) fiber solutions tenants. As a leading provider of shared communications infrastructure in the U.S., our strategy is to create long-term stockholder value via a combination of (1) growing cash flows generated from our portfolio of communications infrastructure, (2) returning a meaningful portion of our cash generated by operating activities to our stockholders in the form of dividends, and (3) investing capital efficiently to grow cash flows and long-term dividends per share. Our strategy is based, in part, on our belief that the U.S. is the most attractive market for shared communications infrastructure investment with the greatest long-term growth potential. We measure our efforts to create "long-term stockholder value" by the combined payment of dividends to stockholders and growth in our per share results.
We have engaged, and expect to continue to engage, in discretionary investments that we believe will maximize long-term stockholder value. Our historical discretionary investments include (in no particular order): constructing communications
22


infrastructure, acquiring communications infrastructure, acquiring land interests (which primarily relate to land assets under towers), improving and structurally enhancing our existing communications infrastructure, purchasing shares of our common stock, and purchasing, repaying, or redeeming our debt. We have recently spent, and expect to continue to spend, a significant percentage of our discretionary investments on the construction of small cells and fiber. We seek to fund our discretionary investments with both net cash generated by operating activities and cash available from financing capacity, such as the use of our undrawn availability from the 2016 Revolver, issuances under our CP Program, debt financings and issuances of equity or equity-related securities, including under our 2021 ATM Program.
We seek to maintain a capital structure that we believe drives long-term stockholder value and optimizes our weighted-average cost of capital. We target a leverage ratio of approximately five times Adjusted EBITDA, subject to various factors, such as the availability and cost of capital and the potential long-term return on our discretionary investments. We may choose to increase or decrease our leverage from this target for various periods of time. We have no significant contractual debt maturities until 2023 (other than Commercial Paper Notes that may be outstanding from time to time and principal payments on certain outstanding debt).
We operate as a REIT for U.S. federal income tax purposes. We expect to continue to pay minimal cash income taxes as a result of our REIT status and our NOLs. See note 6 to our condensed consolidated financial statements and also the 2021 Form 10-K.
Liquidity Position. The following is a summary of our capitalization and liquidity position as of March 31, 2022. See "Item 3. Quantitative and Qualitative Disclosures About Market Risk" and note 4 to our condensed consolidated financial statements for additional information regarding our debt, as well as note 9 to our condensed consolidated financial statements for additional information regarding our 2021 ATM Program.

Over the next 12 months:
Our liquidity sources may include (1) cash on hand, (2) net cash generated by our operating activities, (3) undrawn availability under our 2016 Revolver, (4) issuances under our CP Program, and (5) issuances of equity pursuant to our 2021 ATM Program. Our liquidity uses over the next 12 months are expected to include (1) debt obligations of $1.1 billion (consisting of Commercial Paper Notes and principal payments), (2) cumulative common stock dividend payments expected to be at least $5.88 per share, or an aggregate amount of approximately $2.5 billion (see "Item 2. MD&A—Business Fundamentals and Results") and (3) capital expenditures. We may also purchase shares of our common stock. Additionally, amounts available under the CP Program may be repaid and re-issued from time to time. During the next 12 months, while our liquidity uses are expected to exceed our net cash provided by operating activities, we expect that our liquidity sources described above should be sufficient to cover our expected uses. Historically, from time to time, we have accessed the capital markets to issue debt and equity.
See "Item 3. Quantitative and Qualitative Disclosures About Market Risk" and note 4 to our condensed consolidated financial statements for a tabular presentation of our debt maturities and a discussion of anticipated repayment dates.

Net increase (decrease) in cash, cash equivalents, and restricted cash $16 $57 $(41)
Operating Activities
Net cash provided by operating activities of $558 million for the first three months of 2022 decreased by $26 million, or 4%, compared to the first three months of 2021, due primarily to a net decrease from changes in working capital, which was partially offset by growth in our core business. Changes in working capital contribute to variability in net cash provided by operating activities, largely due to the timing of advanced payments by us and advanced receipts from tenants. We expect to grow our net cash provided by operating activities in the future (exclusive of changes in working capital) if we realize expected growth in our core business.
Investing Activities
Net cash used for investing activities of $289 million for the first three months of 2022 decreased by $22 million, or 7%, from the first three months of 2021 primarily as a result of decreased discretionary capital expenditures in our Fiber segment.
Capital Expenditures
Our capital expenditures are categorized as discretionary or sustaining as described below.
Discretionary capital expenditures are made with respect to activities which we believe exhibit sufficient potential to enhance long-term stockholder value. They primarily consist of expansion or development of communications infrastructure (including capital expenditures related to (1) enhancing communications infrastructure in order to add new tenants for the first time or support subsequent tenant equipment augmentations or (2) modifying the structure of a communications infrastructure asset to accommodate additional tenants) and construction of new communications infrastructure. Discretionary capital expenditures also include purchases of land interests (which primarily relate to land assets under towers as we seek to manage our interests in the land beneath our towers), certain technology-related investments necessary to support and scale future customer demand for our communications infrastructure, and other capital projects. The expansion or development of existing communications infrastructure to accommodate new leasing typically varies based on, among other factors: (1) the type of communications infrastructure, (2) the scope, volume, and mix of work performed on the communications infrastructure, (3) existing capacity prior to installation, or (4) changes in structural engineering regulations and standards. Currently, construction of new communications infrastructure is predominately comprised of the construction of small cells and fiber (including certain construction projects that may take 18 to 36 months to complete). Our decisions regarding discretionary capital expenditures are influenced by the availability and cost of capital and expected returns on alternative uses of cash, such as payments of dividends and investments.
Sustaining capital expenditures consist of those capital expenditures not otherwise categorized as discretionary capital expenditures, such as (1) maintenance capital expenditures on our communications infrastructure assets that enable our tenants' ongoing quiet enjoyment of the communications infrastructure and (2) ordinary corporate capital expenditures.

Capital expenditures for the three months ended March 31, 2022 and 2021 were as follows:

(a)Towers segment includes $16 million and $18 million of capital expenditures incurred during the three months ended March 31, 2022 and 2021, respectively, in connection with tenant installations and upgrades on our towers.
Discretionary capital expenditures were primarily impacted by the timing of Fiber tenant activity during the first three months of 2022 compared to the same period in 2021. See also "Item 2. MD&A—General Overview—Outlook Highlights" for our expectations surrounding 2022 capital expenditures.
Financing Activities. We seek to allocate cash generated by our operations in a manner that will enhance long-term stockholder value, which may include various financing activities such as (in no particular order): (1) paying dividends on our common stock (currently expected to total at least $5.88 per share over the next 12 months, or an aggregate amount of approximately $2.5 billion); (2) purchasing our common stock or (3) purchasing, repaying, or redeeming our debt. See notes 4 and 9 to our condensed consolidated financial statements.
Net cash used for financing activities of $253 million for the first three months of 2022 increased by $36 million from the first three months of 2021 as a result of the net impact from our issuances, purchases and repayments of debt (including with respect to our 2016 Credit Facility and CP Program), common stock dividend payments and purchases of our common stock. See Item 2. MD&A—General Overview—Business Fundamentals and Results and notes 4 and 9 to our condensed consolidated financial statements for further information.
In March 2022, we issued $750 million aggregate principal amount of senior unsecured notes, the net proceeds of which were used to repay a portion of the outstanding indebtedness under our CP Program and pay related fees and expenses.

In March 2022, we (1) prepaid in full the previously outstanding Tower Revenue Notes, Series 2018-1 and (2) redeemed in full the previously outstanding 3.849% Secured Notes.
Credit Facility.
The proceeds of our 2016 Revolver may be used for general corporate purposes, which may include the financing of capital expenditures, acquisitions and purchases of our common stock. As of April 26, 2022, we had an outstanding balance of $180 million and $4.8 billion in undrawn availability under our 2016 Revolver. See note 4 to our condensed consolidated financial statements for additional information regarding our Credit Facility.
Commercial Paper Program. See "Item 2. MD&A—General Overview—Overview" and note 4 to our condensed consolidated financial statements for further information regarding our CP Program. In March 2022, we increased the size of our CP Program to permit the issuance of Commercial Paper Notes in an aggregate principal amount not to exceed $2.0 billion at any time outstanding. The proceeds from our Commercial Paper Notes may be used for general corporate purposes, which may include the financing of capital expenditures, acquisitions and purchases of our common stock. As of April 26, 2022, there was $1.5 billion outstanding under our CP Program.
Incurrence, Purchases, and Repayments of Debt. See "Item 2. MD&A—General Overview—Highlights of Business Fundamentals and Results" for further discussion of our recent issuances, purchases, redemption and repayments of debt.
Common Stock Activity. See note 9 to our condensed consolidated financial statements for further information regarding our common stock and dividends.
25


ATM Program.
In March 2021, we established the 2021 ATM Program through which we may issue and sell shares of our common stock having an aggregate gross sales price of up to $750 million. Sales under the 2021 ATM Program may be made by means of ordinary brokers' transactions on the NYSE or otherwise at market prices prevailing at the time of sale, at prices related to prevailing market prices or, subject to our specific instructions, at negotiated prices. We intend to use the net proceeds from any sales under the 2021 ATM Program for general corporate purposes, which may include (1) the funding of future acquisitions or investments or (2) the repayment or repurchase of any outstanding indebtedness. We have not sold any shares of common stock under the 2021 ATM Program.
Debt Covenants. Our Credit Agreement contains financial maintenance covenants. We are currently in compliance with these financial maintenance covenants and, based upon our current expectations, we believe we will continue to comply with our financial maintenance covenants. In addition, certain of our debt agreements contain restrictive covenants that place restrictions on us and may limit our ability to, among other things, incur additional debt and liens, purchase our securities, make capital expenditures, dispose of assets, undertake transactions with affiliates, make other investments, pay dividends or distribute excess cash flow. See the 2021 Form 10-K for a further discussion of our debt covenants, certain restrictive covenants and factors that are likely to determine our subsidiaries' ability to comply with current and future debt covenants.
Accounting and Reporting Matters
Critical Accounting Policies and Estimates
Our critical accounting policies and estimates are those that we believe (1) are most important to the portrayal of our financial condition and results of operations or (2) require our most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. In many cases, the accounting treatment of a particular transaction is specifically prescribed by GAAP. In other cases, management is required to exercise judgment in the application of accounting principles with respect to particular transactions. Accordingly, actual results could differ materially from our estimates. Our critical accounting policies and estimates as of December 31, 2021 are described in "Item 7. MD&A—Accounting and Reporting Matters" and in note 2 of our consolidated financial statements in the 2021 Form 10-K.
Accounting Pronouncements

See note 2 to our condensed consolidated financial statements.
Non-GAAP and Segment Financial Measures
We use earnings before interest, taxes, depreciation, amortization and accretion, as adjusted ("Adjusted EBITDA"), which is a non-GAAP financial measure, as an indicator of consolidated financial performance. Our measure of Adjusted EBITDA may not be comparable to similarly titled measures of other companies, including companies in the communications infrastructure sector or other REITs, and is not a measure of performance calculated in accordance with GAAP. Adjusted EBITDA should not be considered in isolation or as a substitute for operating income (loss), income (loss) from continuing operations, net income (loss), net cash provided by (used for) operating, investing and financing activities or other income statement or cash flow statement data prepared in accordance with GAAP and should be considered only as a supplement to income (loss) from continuing operations computed in accordance with GAAP as a measure of our performance. There are material limitations to using a measure such as Adjusted EBITDA, including the difficulty associated with comparing results among more than one company, including our competitors, and the inability to analyze certain significant items, including depreciation and interest expense, that directly affect our net income or loss. Management compensates for these limitations by considering the economic effect of the excluded expense items independently as well as in connection with their analysis of income (loss) from continuing operations.
We define Adjusted EBITDA as income (loss) from continuing operations plus restructuring charges (credits), asset write-down charges, acquisition and integration costs, depreciation, amortization and accretion, amortization of prepaid lease purchase price adjustments, interest expense and amortization of deferred financing costs, (gains) losses on retirement of long-term obligations, net (gain) loss on interest rate swaps, (gains) losses on foreign currency swaps, impairment of available-for-
26


sale securities, interest income, other (income) expense, (benefit) provision for income taxes, cumulative effect of a change in accounting principle and stock-based compensation expense. The reconciliation of Adjusted EBITDA to our income (loss) from continuing operations is set forth below:

Adjusted EBITDA(a)
$1,095 $897 
(a)The above reconciliation excludes the items included in our Adjusted EBITDA definition which are not applicable to the periods shown.
We believe Adjusted EBITDA is useful to investors or other interested parties in evaluating our financial performance because:
it is the primary measure used by our management (1) to evaluate the economic productivity of our operations and (2) for purposes of making decisions about allocating resources to, and assessing the performance of, our operations;
although specific definitions may vary, it is widely used by investors or other interested parties in evaluation of the communications infrastructure sector and other REITs to measure financial performance without regard to items such as depreciation, amortization and accretion, which can vary depending upon accounting methods and the book value of assets;
we believe it helps investors and other interested parties meaningfully evaluate and compare the results of our operations (1) from period to period and (2) to our competitors by removing the impact of our capital structure (primarily interest charges from our outstanding debt) and asset base (primarily depreciation, amortization and accretion) from our financial results; and
it is similar to the measure of current financial performance generally used in our debt covenant calculations.
Our management uses Adjusted EBITDA:
as a performance goal in employee annual incentive compensation;
as a measurement of financial performance because it assists us in comparing our financial performance on a consistent basis as it removes the impact of our capital structure (primarily interest charges from our outstanding debt) and asset base (primarily depreciation, amortization and accretion) from our operating results;
in presentations to our board of directors to enable it to have the same measurement of financial performance used by management;
for planning purposes, including preparation of our annual operating budget;
as a valuation measure in strategic analyses in connection with the purchase and sale of assets;
in determining self-imposed limits on our debt levels, including the evaluation of our leverage ratio and interest coverage ratio; and
with respect to compliance with our debt covenants, which require us to maintain certain financial ratios that incorporate concepts such as, or similar to, Adjusted EBITDA.
In addition to the non-GAAP measures used herein and as discussed in note 10 to our condensed consolidated financial statements, we also provide (1) segment site rental gross margin, (2) segment services and other gross margin, and (3) segment operating profit, which are key measures used by management to evaluate the performance of our operating segments. These segment measures are provided pursuant to GAAP requirements related to segment reporting.
We define segment site rental gross margin as segment site rental revenues less segment site rental costs of operations, excluding stock-based compensation expense and amortization of prepaid lease purchase price adjustments recorded in consolidated site rental costs of operations. We define segment services and other gross margin as segment services and other
27


revenues less segment services and other costs of operations, excluding stock-based compensation expense recorded in consolidated services and other costs of operations. We define segment operating profit as segment site rental gross margin plus segment services and other gross margin, and segment other operating (income) expense, less selling, general and administrative expenses attributable to the respective segment. All of these measurements of profit or loss are exclusive of depreciation, amortization and accretion, which are shown separately. Additionally, certain costs are shared across segments and are reflected in our segment measures through allocations that management believes to be reasonable.

ITEM 3.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
The following section updates "Item 7A. Quantitative and Qualitative Disclosures About Market Risk" in the 2021 Form 10-K and should be read in conjunction with that report as well as our condensed consolidated financial statements included in Part 1, Item 1 of this Form 10-Q.
Interest Rate Risk
Our interest rate risk as of March 31, 2022 relates primarily to the impact of interest rate movements on the following:
the potential refinancing of our existing debt ($21.3 billion outstanding at March 31, 2022 and $20.8 billion at December 31, 2021);
our $3.2 billion and $2.2 billion of floating rate debt at March 31, 2022 and December 31, 2021, respectively, which represented approximately 15% and 10% of our total debt, as of March 31, 2022 and December 31, 2021, respectively; and
potential future borrowings of incremental debt, including borrowings under our 2016 Credit Facility and issuances under the CP Program.
We currently have no interest rate swaps.
Sensitivity Analysis
We manage our exposure to market interest rates on our existing debt by controlling the mix of fixed and floating rate debt. As of March 31, 2022, we had $3.2 billion of floating rate debt, none of which had LIBOR floors. As a result, a hypothetical unfavorable fluctuation in market interest rates on our existing debt of 1/8 of a percent point over a 12 month period would increase our interest expense by approximately $4 million.
Tabular Information
The following table provides information about our market risk related to changes in interest rates. The future principal payments and weighted-average interest rates are presented as of March 31, 2022. These debt maturities reflect final maturity dates and do not consider the impact of the principal payments that commence following the anticipated repayment dates of certain debt (see footnotes (b) and (d)). The information presented below regarding the variable rate debt is supplementary to our sensitivity analysis regarding the impact of changes in the interest rates. See notes 4 and 5 to our condensed consolidated financial statements and the 2021 Form 10-K for additional information regarding our debt.

(a)The fair value of our debt is based on indicative quotes (that is, non-binding quotes) from brokers that require judgment to interpret market information, including implied credit spreads for similar borrowings on recent trades or bid/ask offers. These fair values are not necessarily indicative of the amount which could be realized in a current market exchange.
(b)The impact of principal payments that will commence following the anticipated repayment dates is not considered. The Tower Revenue Notes have principal amounts of $700 million and $750 million, with anticipated repayment dates in 2025 and 2028, respectively.
(c)The average interest rate represents the weighted-average stated coupon rate (see footnote (d)).
(d)If the Tower Revenue Notes are not repaid in full by the applicable anticipated repayment dates, the applicable interest rate increases by approximately 5% per annum and monthly principal payments commence using the Excess Cash Flow (as defined in the indenture governing the applicable Tower Revenue Notes) of the issuers of the Tower Revenue Notes. The Tower Revenue Notes are presented based on their contractual maturity dates ranging from 2045 to 2048 and include the impact of an assumed 5% increase in interest rate that would occur following the anticipated repayment dates but exclude the impact of monthly principal payments that would commence using Excess Cash Flow of the issuers of the Tower Revenue Notes. The full year 2021 Excess Cash Flow of the issuers of the Tower Revenue Notes was approximately $933 million. We currently expect to refinance these notes on or prior to the respective anticipated repayment dates.
(e)See note 7 to our consolidated financial statements in the 2021 Form 10-K for information regarding potential upward or downward adjustments to the interest rate spread and unused commitment fee percentage on our 2016 Credit Facility if we achieve specified annual sustainability targets or fail to meet annual sustainability thresholds. Each period presented assumes the downward adjustments in the interest rate spread and unused commitment fee percentage on our 2016 Credit Facility.
(f)Predominately consists of outstanding indebtedness under our CP Program. Such amounts may be issued, repaid or re-issued from time to time.
